Hey guys so I'm in the shit, purchased a power fc and injectors went to get fitted today, they fitted it and tuned for about 3 hours mapping everything and they turned the car off came back started it and power fc lost all the maps and is running like shit. Spoke to the previous owner of ecu ran fine 100% and has been tuned in his car 4 times no problems supposedly there is a problem with a relay that supply's power to the ecu when the key is turned off or something.

Thankyou for your fast response 89cal I'll let my mechanic know tomorow, I wouldn't have thought my cars wiring would have been altered as it used to have a power fc in it before I bought it but I guess you never know what previous owners have done

Maybe that is the problem as I have had a viper alarm fitted since having the original power fc in it. Hopefully this will fix the problem thanks for all the input guys

So I got a call this arvo they found a faulty relay they pulled it out and swapped it for a mate of there's and the car ran like a champ, so hopefully that's the end of that. Thanks everybody for the help your gentleman/woman and scholars
